Detailed description of the invention
As shown in Figure 1, 2:
Frame 1 is in bottom, and hydraulic system 2 centralized arrangement is also connected to frame 1 upper left side, is connected respectively by epicoele oil pipe 10, lower cavity oil pipe 11 with the epicoele of oil cylinder 8, cavity of resorption; Lathe bed 3 is fixed on frame 1 upper right side, is the workbench 4 that key dog screw is fixed below lathe bed 3 front, and oil cylinder 8 is arranged in the middle of cylinder bracket 9, and cylinder bracket 9 is fixed on fuselage 3 upper front by key location; Transformer 13 is fixed on lathe bed 3 bosom, bottom electrode 5 is fixed on workbench 4 end face, connected with output under transformer 13 secondary coil by hard wire 14, top electrode 6 is fixed on piston rod 7 end of oil cylinder 8, connected with output on transformer 13 secondary coil by flexible circuit conductor 12, do not affect top electrode 6 with the upper and lower motion of piston rod 7.
The utility model application process illustrates:
Bottom electrode 5 is fixed on workbench 4 end face, is connected with output under transformer 13 secondary coil being fixed on lathe bed 3 inside by hard wire 14, and upper vice body 16, lower vice body 17 and pliers rotating shaft 15 are gone here and there conjunction and be placed on bottom electrode 5 end face.Top electrode 6 is fixed on the end of piston rod 7, is connected by the upper output of flexible circuit conductor 12 with transformer 13 secondary coil.At the oily epicoele being entered oil cylinder 8 by epicoele oil pipe 10 of the control downforce of hydraulic system 2, piston rod 7 is descending with top electrode 6, a power circuit is formed after its end face contacts with pliers rotating shaft 15 end face, now energising starts heating, and within the whole heat time, top electrode 6 keeps the duty of descending pressurization under the promotion of piston rod 7.From Fig. 3 (1), now resistance maximum is top electrode 6 and pliers rotating shaft 15 top contact surface, under the effect of low-voltage and high-current, this place's temperature rises rapidly, pliers rotating shaft under external force 15 top produces distortion, distortion makes this place's sectional area increase, and resistance reduces, and resistance maximum moves down bottom deformed area, the metal material heating this place while movement makes it participate among distortion, and its position is seen shown in Fig. 3 (2) " A ".This change continues to carry out within the heat time, and the heat that in process, resistance maximum produces makes deformed area material temperature remain on a stable numerical value in the mode of conduction, thus ensure that the riveting quality of pliers rotating shaft.This process lasts carries out until the heat time terminates, i.e. Fig. 3 (3).Now hydraulic system 2 commutates, and pressure oil enters oil cylinder 8 cavity of resorption by lower cavity oil pipe 11, and piston rod 7 goes upward to summit with top electrode 6, and process terminates.
The needs that the utility model employing hydraulic drive can provide larger pressure to be out of shape to meet workpiece riveted, meet the riveted needs of all size pliers rotating shaft by adjustment heating current, heat time after pressure is determined, owing to being digital control, adjust very convenient, simple, ensure that the rigidity in riveted process needs to further provide the operating space of 270 °, provide more selection to automation group line.
